Document config parameters for each Map-Reduce class/interface
--------------------------------------------------------------
Key: HADOOP-2122
URL: https://issues.apache.org/jira/browse/HADOOP-2122
Project: Hadoop
Issue Type: Improvement
Components: documentation
Reporter: Arun C Murthy
I propose we add a table in the javadoc for each user-facing Map-Reduce
interface/class which lists, and provides details, of each and every config
parameter which has any bearing on that interface/class. Clearly some
parameters affect more than one place and they should be put in more than one
table.
For e.g.
Mapper -> io.sort.mb, io.sort.factor
Reducer -> fs.inmemory.size.mb
...
etc.
It would very nice to explain how it interacts with the framework and rest of
config params etc.
Thoughts?
